Subject: [PATCH v8 01/13] squash! max9286: Update the bound_sources mask on unbind
Date: Thu,  9 Apr 2020 13:11:50 +0100	[thread overview]
Message-ID: <20200409121202.11130-2-kieran.bingham+renesas@ideasonboard.com> (raw)
In-Reply-To: <20200409121202.11130-1-kieran.bingham+renesas@ideasonboard.com>

The bound_sources bit mask tracks sources which have been successfully
bound through the v4l2 async notifier system.

Ensure that the mask is updated accordingly when unbinding.
